FIG. 4 is a diagram for explaining a method for changing an access point(AP) among methods for providing a vehicle based communication serviceaccording to an exemplary embodiment of the present disclosure.Referring to FIG. 4, in a method for changing the AP of the presentdisclosure, first, the vehicle 101 performs to enter the AP mode at stepS101. The vehicle 101 may enter the AP mode according to the input ofthe user or the scheduled information. The vehicle 101 activates thehigh-speed short distance communicator 120 in order to enter the APmode, thereby preparing to operate the AP mode.

At step S102, the vehicle 102 may attempt the connection with the AP andbe connected with the AP. In addition, at step S103, the vehicle 103 mayattempt the connection with the AP and be connected with the AP. Thevehicles 102 and 103 search around the vehicle in order to attempt theconnection with AP, and may scan the high-speed short distancecommunicator disposed in the vehicle 101. In addition, the vehicles 102and 103 automatically attempt the connection with the AP and perform theconnection with the AP according to the input of the user or based onidentification information of the vehicle 101.

At step S105, the vehicles 101, 102, and 103 may share the TM UNITinformation, the access key value, and the like for changing the APlater. Here, each of the vehicles 101, 102, and 103 may share all H/U(TM) connected with the AP. That is, the vehicles 101, 102, and 103share the identification information and the access key value oneanother, and may build a certain closed short distance network.

Next, at step S107, the vehicle 101 may determine and notify BPS lowerthan reference speed. Here, the vehicle 101 may check the datatransmission rate according to a certain period, or check the datatransmission rate in real time. In addition, if the data transmissionrate falls below the certain BPS, that is, if it is determined that thecommunication environment is not good as compared to a predefinedcertain condition, the vehicle 101 may transfer the notification forthis to other vehicles.

At step S109, the vehicle 101 may determine the signal strength BPS of aconnectable network. In addition, each of the vehicles 102 and 103determines the signal strength BPS of the connectable network at stepS110 and step S111 and may transfer the determined information. That is,each of the vehicles 101, 102, and 103 may check for the signalenvironment of its own data communication network. Each of the vehicles101, 102, and 103 may collect information on the signal strength, thedata transmission rate, and the like during this process. When theinformation on the communication environment including the signalstrength information and the data transmission rate information arecollected, each of the vehicles 102 and 103 may transfer thecorresponding information to the vehicle 101.

Next, at step S113, the vehicle 101 determines the best BPS AP and maytransfer the information to the vehicles 102 and 103. The vehicle 101may compare the information on the communication environment receivedfrom the other vehicles 102 and 103 with the information on thecommunication environment collected by the vehicle 101. The vehicle 101may transfer the comparison results to the other vehicles 102 and 103.Here, the vehicle 101 may also transfer the information on which vehiclehas the best communication environment.

When it is determined that the vehicle 102 is the best at step S113, thevehicle 102 may enter the AP mode at step S115. That is, when the resultthat the communication environment of the vehicle 102 is the best isreceived from the vehicle 101, the vehicle 102 may enter the high-speedshort distance communicator in the AP mode. Therefore, at step S116, thevehicle 101 may attempt the AP connection with the vehicle 102 andperform the connection with the vehicle 102. Similarly, the vehicle 103may attempt the AP connection with the vehicle 102 and perform theconnection with the AP.

When setting the above-mentioned vehicle AP network, the vehicles 101,102, and 103 use a specific platform sharing key and a separate key forsetting a closed network to thereby support the operation of the shortdistance network between limited vehicles. In addition, the vehicles101, 102, and 103 may confirm the device which is able to enter the APmode firstly. That is, the vehicles 101, 102, and 103 confirm a vehiclewhich is able to access to the communication network 300, and set arelatively good vehicle to enter the AP mode by comparing theinformation on the communication environment one another when theplurality of vehicles are able to access to the wireless mobilecommunication network 300. The vehicles 101, 102, and 103 create a linkfor real time BPS sharing, and may operate to select the vehicle havingthe best BPS as the AP mode. The evaluation of the BPS may be defined asthe average value within the reference time. In addition, as describedabove, when the change of BPS occurs, the vehicles 101, 102, and 103 mayperform a procedure for the AP reselection. At this time, the operationof the AP may be temporarily stopped during the AP reselection period,and signal processing of each of the vehicles 101, 102, and 103 may beperformed so as to resume the operation of the network after reselectingthe AP.
